FEVE Emulsions in Architectural Coatings Outline: Overview of “FEVE” resin technology Introduction of water-based “FEVE” emulsions Formulations using “FEVE” emulsions as blending resins QUV Exposure Testing – gloss and color retention Examination of exposed paint films
FEVE Emulsions in Architectural Coatings FEVE Fluoropolymer Resins “FEVE” is abbreviation for “Fluoroethylene Vinyl Ether” resins for coatings Known for their high performance properties: Exceptional resistance to UV degradation Superior Chemical Resistance Excellent Thermal Resistance - Known for their unique formulation properties: 1) Solvent soluble 2) Can be cured at ambient temperature with isocyanates 3) Can achieve high gloss formulations
Fluoroethylene Vinyl Ether (FEVE) Resins FLUORINATED SEGMENTS: Weatherability, durability, chemical resistance VINYL ETHER SEGMENTS: Gloss, solubility, crosslinking
FEVE Emulsions in Architectural Coatings Commercial Types of “FEVE” Resins: Solvent soluble resins – uses organic solvents for viscosity reduction; predominantly cured with isocyanates; available as resin solutions or as 100% solid resins 2) Water-based emulsions – use vinyl ether macromonomers containing polyoxyethylene (EO) units to create stable emulsions

FEVE Emulsions in Architectural Coatings Conclusion: Inclusion of FEVE emulsions in architectural coating formulations can increase gloss retention, color retention, and the overall durability of the dry film. These characteristics will prolong the aesthetic properties and the protection properties of these coatings, thereby increasing the time frame between recoats.
